Yellowstone wolf ( Canis lupus ) density predicted by elk ( Cervus elaphus ) biomass
The Northern Range (NR) of Yellowstone National Park (YNP) hosts a higher prey biomass density in the form of elk (Cervus elaphus L., 1758) than any other system of gray wolves (Canis lupus L., 1758) and prey reported. Therefore, it is important to determine whether that wolf–prey system fits a long...

description | The Northern Range (NR) of Yellowstone National Park (YNP) hosts a higher prey biomass density in the form of elk (Cervus elaphus L., 1758) than any other system of gray wolves (Canis lupus L., 1758) and prey reported. Therefore, it is important to determine whether that wolf–prey system fits a long-standing model relating wolf density to prey biomass. Using data from 2005 to 2012 after elk population fluctuations dampened 10 years subsequent to wolf reintroduction, we found that NR prey biomass predicted wolf density. This finding and the trajectory of the regression extend the validity of the model to prey densities 19% higher than previous data and suggest that the model would apply to wolf–prey systems of even higher prey biomass. Le domaine nord (Northern Range; NR) du parc national de Yellowstone (YNP) contient une biomasse de proies de plus grande densité, représentée par les wapitis (Cervus elaphus L., 1758), que tout autre système de loups gris (Canis lupus L., 1758) et proies connu. Il importe donc de déterminer si le système loups–proies concorde avec un modèle établi de longue date qui relie la densité des loups a` la biomasse des proies. En nous servant de données de 2005 a` 2012 après l’atténuation sur une période de 10 ans des fluctuations de la population de wapitis a` la suite de la réintroduction des loups, nous avons constaté que la biomasse des proies du NR prédisait la densité des loups. Cette constatation et la trajectoire de la régression élargissent la validité du modèle a` des densités de proies de 19 % supérieures aux données antérieures et donnent a` penser que le modèle s’appliquerait a` des systèmes loups–proies de biomasse de proies encore plus grande. |
